What Mac exactly are you using,
what Mac OS X version is on it,
with what FCP version do you work,
what cable do you use,
has it worked before
(if so, what happened since then),
what footage is on tape (DV or HDV),
have you set the FX1 to PLAY/VCR mode?

Please provide that information, and we might be able to give you help.

I had that camera some years ago and it worked fine with FCP, with DV and HDV material.
